Hi All!
For a customer i need to extract objects like shapes, lines, boxes, graphical logos from a document. There's no need doing a real extract but detect all object data like type of the object, color, dimensions, ... At first i don't need a complete solution but are there any ideas from anyone here, how i should start? Thanks in advance for any hint and advice. Cheers, Ingo |

Hi ingo
I think it would not be possible in the state of QuickPdf, because the page is drawn by parsing it's content without creating graphicals objects . It's just drawn on a bitmap. So individual elements are'nt save and can't be retreived.

Hi Ingo,
You could try the following: 1. Render the page to an EMF file 2. Load the EMF and enumerate it using Win32 functions As a side note: We will also investigate the feasibility of implementing a text-based logging system for the renderer, which should give you the information you need. Cheers, Rowan |
